Just finished up a track weekend at Road Atlanta with Hawk DTC 30 pads (front)... much improved braking. No significant decrease in braking from the start of the sessions to the end (30 minutes).

Now it is time to swap back to the Hawk street pad, so looking for any advice from those that are pros at this. Hoping to try it without removing the calipers, so if someone has been doing this, please give me some insight.

This was also the first time out with the Michelin Super Sports....what a great tire. Highly recommend for anyone who is looking for a street/track tire. Expensive, but worth every penny coming down the hill to turn 12!

I had understood that it's not a good idea to swap pad types without turning the rotors, because the residual material from the previous pad is still on the disk and prevents proper braking with the new pad.

But I've also heard that you can do just what you're doing- swap in track pads at the track, then swap back.

Are there any brake gurus out there that could shed some light on which is true?

Typically if you stick with the same manufacturer their compounds are compatible but it doesn't hurt to ask before purchasing. But yes pad residue from an old pad can cause overheating and poor performance leading to gunked up everything with embedded pad/rotor material.

Road racing is like China White Heroin, the buzz is stronger, the high lasts for hours, it's extremely addictive and they are all different. I can't wait for my next Track fix. DA HAWKS OWN DA CUP!!!!!
